Product Description

High voltage circuirt breaker testerDescription
XHJJ302B high voltage switch comprehensive tester can test all kinds of domestic (imported) vacuum, sulfur hexafluoride, oil high voltage circuit breakers, load switches, GIS grounding knife switch, contactors, relays, air switches, etc. It can measure various data and waveforms such as circuit breaker time, synchronization, bounce time (Times), line number, permeability, operating voltage, current, operating voltage, mechanical operation, etc. it can withstand micro field 5kV induced voltage, and is equipped with 12 independent metal contact time channel test function as standard.


The high-voltage switch comprehensive tester provides convenience for dynamic analysis of various circuit breakers, and can accurately measure the mechanical and dynamic characteristic parameters of high-voltage circuit breakers such as less oil, more oil, vacuum, sulfur hexafluoride and so on. Mechanical characteristic parameter is one of the important parameters to judge the performance of circuit breaker.
Main Function
(1) large 8.4-inch color screen, windows operating system, humanized operation interface, intuitive interface and touch screen are convenient for on-site operators.
(2) high speed thermal printer, which is convenient for printing test data on site.
(3) the integrated operation power supply in the machine does not need the on-site secondary power supply, and the on-site use is convenient and fast. It can provide dc20 ~ 265V adjustable power supply with current of 20a. Arbitrarily set the action voltage value of opening and closing coils, and do the low-voltage action test of circuit breaker.
(4) equipped with linear sensor, rotary sensor, universal sensor, support and special fixed multifunctional connector, the installation is very convenient and simple.
(5) it is applicable to all models of SF6 switches, GIS combination appliances, vacuum switches and oil switches produced at home and abroad.
(6) the switch acts once to obtain all data and graphics.
(7) the host can store 6000 groups of current test data (expandable memory card), and the real-time clock in the host is convenient for archiving.
(8) equipped with USB flash disk interface, the data can be directly saved to USB flash disk and uploaded to the computer for analysis and storage.
(9) at the same time, it can measure the fracture of 12 metal contacts, 6 closing resistance .
(10) envelope is included. The standard envelope is generated through the test values of multiple (2-10) switches for analysis and comparison, and the vibration frequency of switches can also be analyzed.
(11) the internal anti-interference circuit can meet the reliable use in 500kV substation.
